  • 1.  Support for GDA2020 MGA55 (EPSG 7855) as a base layer

    Posted 23 days ago

    Hi,

    I haven't been able to find a specific answer as to whether EPSG 7855 is supported as a base layer in SSA. My experience in SSA v2018.1 is as follows:

    1. Business layers are in EPSG 7855 and display with no problem.
    2. Within Project Settings, I add a EPSG 7855 tile layer (created in Spatial Manager) as a base map and set it as default.
    3. Within the Extents tab I specify the new base layer:

    After saving settings and selecting the project within SSA, the coordinate system in use defaults to a different projection - seemingly taken from the next base layer available (Bing, in this case):

    Note that projected GDA94 (EPSG 28355) is supported as a base layer in 2018.1.

    My questions are:

    A) Are my findings correct - that EPSG 7855 is not supported as a base layer in 2018.1?

    B) If so, in which layer is it supported (if any)?

    C) If it is not supported, what is the recommended approach?

    Thanks.

    Hi James,

    I suspect it might be a version issue as its look good in version 2023.1

    Sorry I don't have a 2018.1 test server anymore.
